Phys.org / Rare 'universal paralog' genes may reveal a pre-LUCA evolutionary record
All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called "last universal common ancestor" (LUCA) represents the most ancient organism that researchers can study. Previous research ...
Phys.org / Solid, iron-rich megastructure under Hawaii slows seismic waves and may drive plume upwelling
Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...
Tech Xplore / A bot-only social media platform: What the Moltbook experiment is teaching us about AI
What happens when you create a social media platform that only AI bots can post to? The answer, it turns out, is both entertaining and concerning. Moltbook is exactly that—a platform where artificial intelligence agents ...
Phys.org / DNA provides a solution to our enormous data storage problem
Since the dawn of the computer age, researchers have wrestled with two persistent challenges: how to store ever-increasing reams of data and how to protect that information from unintended access. Now, researchers with Arizona ...
Medical Xpress / Genetic study shows that anxiety disorders have many causes
About 1 in 4 people suffer from an anxiety disorder at some point in their lives. These include panic disorder with sudden, severe anxiety attacks; generalized anxiety disorder, in which sufferers worry about everyday things ...
Phys.org / A smarter way to watch biology at work: Microfluidic droplet injector drastically cuts sample consumption
Watching proteins move as they drive the chemical reactions that sustain life is one of the grand challenges of modern biology. In recent years, X-ray free-electron lasers, or XFELs, have begun to meet that challenge, capturing ...
Tech Xplore / GeSn alloys emerge as a new semiconductor class that could reshape optoelectronics
Scientists have created a new type of material that could enable common electronic devices to work faster and use less energy, a study suggests. The findings indicate the material, which was until now thought near-impossible ...
Phys.org / Faster enzyme screening could cut biocatalysis bottlenecks in drug development
A team of biochemists at the University of California, Santa Cruz, has developed a faster way to identify molecules in the lab that could lead to more effective pharmaceuticals. The discovery advances the rapidly growing ...
Medical Xpress / Saline nasal spray alone resolves sleep-disordered breathing in nearly one-third of children, study finds
Investigators based at Monash Children's Hospital and Royal Children's Hospital Melbourne report that a once-daily intranasal saline spray resolved obstructive sleep-disordered breathing symptoms in nearly one-third of children ...
Phys.org / Listening to polymers collapse: 'Water bridges' pull the strings
It is not easy to follow the interactions of large molecules with water in real time. But this can be easier to hear than to see. This is how an international team deciphered the role of water in the collapse of PNIPAM.
Phys.org / Surgery for quantum bits: Bit-flip errors corrected during superconducting qubit operations
Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and engineers with a series of challenges and conundrums. One of them relates to decoherence and the ...
Phys.org / Seeds 'listen' to mom: Study finds mother plants send ABA hormone signals that set seed dormancy
Whatever challenges life throws, mothers often know best as they guide offspring through the risky stages of early development. This scenario, familiar when applied to humans, turns out to be true for plants too, according ...
